Abstract

The retained fraction of the potential energy of argon ions incident on copper has been measured using stationary calorimetry at charge states up to $9 +$ and kinetic energies ranging from 75 to 240 eV per ionic charge. An average fraction of $30 %$ to $40 %$ is found with little dependence on the charge number and on the kinetic energy. The retention of the total energy ranges from $60 %$ to $75 %$ and can mainly be accounted for by the retained fraction of the potential energy and the collisional energy lost by reflected ions and sputtered target atoms.
